Chromosome - Wikipedia
A chromosome (/ ˈ k r oʊ m ə ˌ s oʊ m, -ˌ z oʊ m /; from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material of an organism.Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable ...
Y chromosome - Wikipedia
The Y chromosome is one of two sex chromosomes in mammals, including humans, and many other animals.The other is the X chromosome.Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction.In mammals, the Y chromosome contains the gene SRY, which triggers testis development.

Basic Principles of Genetics: Glossary of Terms
alternate forms or varieties of a gene.The alleles for a trait occupy the same locus or position on homologous chromosomes and thus govern the same trait. However, because they are different, their action may result in different expressions of that trait.
